TECHNICAL FIELD

The present application relates to the field of communications and, for example, to an information transmission and receiving method and device, a storage medium and an electronic device.

BACKGROUND

In a wireless communication system, a transmitting end and a receiving end generally use multiple antennas for transmission and reception to obtain a higher communication rate. One principle of the multiple-input-multiple-output (MIMO) technology is to utilize some channel characteristics to form multi-layer transmission that matches the channel characteristics, so that effectively improving system performance is effectively improved, and the significant improvement on the system performance is achieved without increasing a bandwidth and power.

Generally speaking, a complete channel state information (CSI) includes a rank indicator (RI), a precoding matrix indicator (PMI), and a channel quality indicator (CQI) or a channel resource indicator (CRI). In a wireless system, the CSI is transmitted as a type of uplink control information (UCI), which can be transmitted on a physical uplink control channel (PUCCH) or on a physical uplink shared channel (PUSCH). In addition to the CSI, the UCI may also include hybrid automatic repeat request-acknowledge (HARQ-ACK) information and/or scheduling request (SR) information, where an ACK/NACK feedback is transmitted in the HARQ-ACK information, a scheduling request of the terminal is transmitted in the SR information.

In the related art, the terminal encodes and transmits the CSI through two modes. In a first mode, the channel encoding and transmission are performed on all CSI parameters in a CSI report. In a second mode, the CSI report is divided into two parts. The two parts are encoded and reported separately. In the two modes, there is no effective solution for multiplexing, encoding and transmitting the CSI and data information or the CSI and other UCI in the related art.

This embodiment provides an information receiving method executed by the mobile terminal described above. FIG. 3 is a flowchart of the information receiving method according to the embodiment of the present application. As shown in FIG. 3 , the method includes steps S202 and S204 described below.

In step S202, at least two pieces of information in the following information are acquired: CSI, first control information or data information; where the first control information includes at least one of: hybrid automatic retransmission request acknowledgement (HARQ-ACK) information or scheduling request (SR) information.

In step S204, the acquired at least two pieces of information are transmitted in a multiplexing manner on a physical channel.

Through the above steps, at least two pieces of the following information are transmitted in the multiplexing manner on a physical channel: the CSI, the first control information or the data information, i.e., transmitting the data information and the second control information (including the CSI and/or the first control information) in the multiplexing manner or transmitting the CSI and the first control information in the multiplexing manner on a physical channel. Therefore, the transmission efficiency of the control information and the data information may be increased, and the problem of low transmission efficiency of the control information and the data information in the related art may be solved.

It should be noted that the above S202 may be omitted, but it is not limited thereto.

It should be noted that the above physical channel may include at least one of: a physical uplink control channel (PUCCH) and a physical uplink shared control channel (PUSCH).

In an embodiment of the present application, in condition that the at least two pieces of information include the CSI or the first control information, the above S204 may be expressed as one of: manner one, performing a jointly encoding transmission on the first control information and all information of the channel state information (CSI) on the physical channel; manner two, performing the jointly encoding transmission on the first control information and first part of information of the channel state information (C SI) on the physical channel, and performing a separately encoding transmission on second part of information of the channel state information (CSI) on the physical channel.

It is to noted that the first part of information may include at least one of: a rank indicator, a channel quality indicator corresponding to a first transmission codeword, a number of non-zero amplitude coefficients, a reference signal resource indicator, a layer-1 reference signal received power (L1-RSRP), or layer indicator (LI) information. The second part of information includes at least one of: a precoding matrix indicator and a channel quality indicator corresponding to a second transmission codeword.

It is to be noted that the CSI includes at least one of: the PMI, the CQI, the RI, reference signal resource indication information, the L1-RSRP and the LI.

It is to be noted that in response to satisfying at least one of conditions, transmission is performed in the manner one: the CSI transmitted on the physical channel being wideband CSI or partial-band CSI; a feedback mode of the PMI being configured to one of: a wideband PMI, a partial-band PMI or a single PMI; a feedback mode of the CQI being configured to one of: a wideband CQI, a partial-band CQI and a single CQI; transmitting, by a terminal, the first control information by using a physical uplink control channel format 3 (PUCCH format 3) or a physical uplink control channel format 4 (PUCCH format 4); and the terminal being configured to allow the terminal to simultaneously transmit the CSI and the first control information on the physical channel.

It is to be noted that configuring the feedback mode of the PMI to the wideband PMI means that the fed back PMI represents PMI information of an entire CSI feedback bandwidth; configuring the feedback mode of the PMI to the partial-band PMI means that the fed back PMI represents a part of all subbands included in an entire activated downlink bandwidth; configuring the feedback mode of the PMI to the single PMI means that the fed back PMI represents an entire CSI reporting bandwidth reporting a single PMI.

It is to be noted that configuring the feedback mode of the CQI to the wideband PMI means that the fed back PMI represents CQI information of an entire CSI feedback bandwidth; configuring the feedback mode of the CQI to the partial-band CQI means that the fed back CQI represents a part of all subbands included in an entire activated downlink bandwidth; configuring the feedback mode of the CQI to the single PMI means that the fed back CQI represents an entire CSI reporting bandwidth reporting a single CQI.

It is to be noted that in response to satisfying at least one of conditions, transmission is performed in the manner two: transmitting subband CSI on the physical channel; the feedback mode of the PMI being configured to at least one of: a subband PMI or multiple PMIs; the feedback mode of the CQI is configured to at least one of: a subband CQI or multiple CQIs; transmitting, by a terminal, the first control information by using a PUCCH format 3 or a PUCCH format 4; and the terminal being configured to allow the terminal to simultaneously transmit the CSI and the first control information on the physical channel.

The above manner limits conditions for transmission in the manner one and conditions for transmission in the manner two, thereby overcoming defects in the related art that how to transmit the CSI and the first control information is not configured, and the transmission efficiency of the control information is improved.

It is to be noted that the control information overhead upper limit may include at least one of: a control information overhead upper limit corresponding to each transmission of the data information; or a control information overhead upper limit corresponding to each redundancy version value of the data information.

Through determining the data code rate upper limit and the control information overhead upper limit, thus the transmission mode for transmitting the data information and/or the control information is determined, so that the problem of not knowing how to multiplex the data information and the control information in the related art can be solved, and the transmission efficiency of the data information and the control information may be improved, the reliability of the data transmission is increased.

It is to be noted that the method may further include: in condition that a sum of resources required for transmitting the channel state information and the data information is less than the allocated channel resources, adjusting the code rate of part or all of the control information of the second control information to match the allocated channel resources.

It is to be noted that an operation of adjusting the code rate of part or all of the control information of the second control information to match the allocated channel resources may be before, after or at the same time of transmitting the second control information and the data information in the same time slot in the multiplexing manner on the physical channel according to the determined transmission mode, but it is not limited thereto.

It is to be noted that the CSI required to be transmitted is determined by a code rate relationship between the second control information and the data information indicated by the base station and a modulation and coding scheme (MCS) of data, but it is not limited thereto.

In an embodiment of the present disclosure, the method further includes: adjusting the code rate for transmitting the data information to match the allocated channel resources according to at least one of: an overhead of the second control information, a data block size, a modulation and coding scheme of the data information, or a code rate relationship between the data information and the second control information.

Exemplary Embodiment Two

This exemplary embodiment gives an implementation of control information and data transmission. A terminal multiplexes data and an UCI on a PUSCH in a same time slot to improve the performance of an uplink transmission. Multiplexing transmission modes are mode 1, mode 2 and mode 3.

Mode one: after calculating the CSI, the terminal obtains the total number of UCI bits, and obtains the total number of resource elements (REs) required by the UCI according to values of β_(offset) of the UCI and an MCS of the PUSCH configured by a base station. The terminal uses the total number of REs of the PUSCH allocated by the base station minus the total number of REs of the UCI to obtain the total number of REs required for the data, and adjusts a code rate of an uplink data transmission to match the total number of data channel resources. FIG. 6 is a schematic diagram of adjusting the data code rate provided by the embodiment two of the present disclosure.

Mode two: when transmitted uplink data is a service with a higher priority, for example, a URLLC service, the reliability of the uplink data transmission needs to be guaranteed. The uplink data may be transmitted according to at least one of following sub-modes. FIG. 7 is a schematic diagram of conditionally adjusting the data code rate according to the exemplary embodiment two of the present disclosure. As shown in FIG. 7 , the mode two includes a sub-mode one and a sub-mode two.

Sub-mode one: the base station configures a code rate upper limit of a multiplexed data transmission for the terminal. A code rate of the transmitted data does not exceed this upper limit. When a code rate of the uplink data transmission is adjusted to reach the upper limit, the code rate is no longer increased for rate matching.

Optionally, the base station may configure multiple code rate upper limits for a total of K transmissions of the same data. A k-th transmission corresponds to an m-th code rate upper limit. When the data is first transmitted and retransmitted, the terminal determines the corresponding code rate upper limit according to this data transmission being the k-th transmission. For example, K transmissions are configured to M groups, a m-th group includes K_(m) transmissions, and the base station configures M code rate upper limits for transmissions of M groups, the m-th code rate upper limit is applied to K_(m) transmissions in the m-th group when K_(m) transmissions multiplex the UCI.

Optionally, the base station may configure multiple upper code rate limits for different redundancy version (RV) values of the same data transmission. When each transmission needs to be multiplexed with the UCI, the terminal determines the corresponding code rate upper limit according to a value of the agreed RV or an indicator of the base station.

Optionally, the base station configures a data transmission code rate upper limit multiplexed with the UCI for each transmission block; another mode is that the base station configures data transmission code rate upper limit multiplexed with the UCI for all transmission blocks, and a maximum value of all transmission block code rates is less than or equal to this code rate upper limit.

Sub-mode two: the base station configures an overhead upper limit of the multiplexed UCI for the terminal. An overhead of the UCI may represent the number of UCI bits, and/or the number of REs occupied by the UCI. The overhead of the UCI transmitted and multiplexed with the data does not exceed the upper limit. When the code rate of the uplink data transmission is adjusted so that the overhead of the UCI reaches the upper limit, the code rate is no longer increased for rate matching.

Optionally, the base station may configure multiple overhead upper limits of the UCI multiplexed by a total of K transmissions of the same data for a total of K transmissions of the same data. The k-th transmission corresponds to the m-th code rate upper limit. When the data is first transmitted and retransmitted, the terminal determines the corresponding overhead upper limit of the UCI multiplexed by the K-th transmission according to this data transmission being the k-th transmission; for example, K transmissions are configured to M groups, the m-th group includes K_(m) transmissions, and the base station configures M overhead upper limits of the UCI for transmissions of M groups, the m-th overhead upper limit is applied to K_(m) transmissions in the m-th group when K_(m) transmissions multiplex the UCI.

Optionally, the base station may configure multiple overhead upper limits of the UCI multiplexed with different RV values of the same data transmission, and when each data transmission needs to be multiplexed with the UCI, the terminal determines the corresponding overhead upper limit of the UCI multiplexed with the data according to the value of the agreed RV or the indicator of the base station.

Mode three: the terminal adjusts a code rate of at least part of the control information to match allocated channel resources according to at least one of an MCS of the data, a control information overhead or a size of the data block required to be transmitted. According to the data MCS indicated by the base station and a relationship between the UCI and the data code rate, if the sum of resources required for transmitting the CSI and the uplink data is less than the allocated channel resources, the code rate of at least part of the control information is adjusted to match the allocated channel resources, for example, a code rate of the second part of CSI included in the CSI required to be transmitted.

For example, a case of mode three is shown in FIG. 8 , FIG. 8 is a schematic diagram of adjusting the code rate of the UCI according to the exemplary embodiment two of the present disclosure. The total number of REs of the PUSCH configured by the base station is N, and the total number of REs of the data obtained from the MCS and the transmission block size (TBS) of the data is N_data. According to the relationship βoffset between the data code rate and the code rate corresponding to the first part and the number of bits in the first part, the total number of REs N_Part1 in the first part of the CSI may be obtained, and the number of bits calculated in the second part of the CSI is B_part2. the total number of REs required to completely transmit Part2 at an original code rate may be obtained according to the β_(offset) and the MCS:

N_Part2_original ∝ B_part2/(MCS/β_(offset)_part2)

N_Part2_original represents the total number of REs required to completely transmit Part2 at the original code rate.

If N_Part2_original<(N−N_data−N_Part1), the code rate of part 2 of the CSI is reduced to

C_part2 ∝ B_part2/(N−N_data−N_part1)

C_part2 represents the code rate after the code rate of part 2 of the CSI is reduced.

Optionally, the base station may instruct the terminal to adopt at least one of the above-mentioned multiple modes through the higher layer signaling or the physical layer signaling. For example, the base station may perform such signaling indicator through different requirements of uplink and downlink services.

Exemplary Embodiment Three

This exemplary embodiment gives an implementation of channel state information feedback. A base station allocates reference signal (RS) resources for a CSI measurement feedback to a terminal, such as CSI-RS resources. These resources include at least one of: a first RS resource set for channel measurement or a second RS resource set for interference measurement. The second RS resource set includes at least one of: an interference measurement resource based on a zero-power RS or an interference measurement resource based on a non-zero-power RS. When performing the CSI calculation, the terminal performs a channel measurement according to resources in the selected first RS resource set, and performs an interference measurement according to one or more second RS resources corresponding to the first RS resource in the second RS resource set. The terminal determines a corresponding relationship between RS resources in the first RS resource set and RS resources in the second RS resource set according to at least one of a first type mode, a second type mode, and a third type mode.

In the first type mode: the base station notifies the terminal of each resource in the first RS resource set as well as which RS resource in the second RS resource set corresponds to each resource in the first RS resource set respectively through higher layer signaling and/or physical layer signaling. For example, the base station may include ID information indicating one or more first RS resource sets corresponding to each second RS resource set in configuration information of each resource included by the second RS resource set or in configuration information in the second RS resource set; or include ID information indicating one or more second RS resource sets corresponding to each first RS resource set in configuration information of each resource included by the first RS resource set or in configuration information in the first RS resource set.

In the second type mode: the terminal acquires the correspondence between the RS resources in the first RS resource set and the RS resources in the second RS resource set by a pre-defined rule. The first RS resource set includes M RS resources {C₁, . . . , C_(M)}, and the second RS resource set includes N RS resources {I₁, . . . , I_(N)}, wherein Ci corresponds to one or more second RS resources I_(i1), I_(i2), . . . , I_(iK). I_(i1), I_(i2), . . . , I_(iK) is several consecutive RS resources in I₁, . . . I_(N). For example, an m-th RS resource in the first RS resource set corresponds to (m−1)K+1 to mK-th RS resources in the second RS resource set, K is an integer greater than or equal to 1, and may be a pre-defined constant, or determined by the configuration signaling of the base station.

If a value of K is determined according to signaling, the signaling may be an explicit signal, or the value of K may be determined according to a ratio between the number of resources included in the configured second RS resource set and the number of resources included in the configured first RS resource set. For example, a ratio of N and M is a real number X, and then the value of K is X or the smallest integer which is larger than X. If the ratio of N and M is less than the value of K (that is, the value of K is an integer after rounding up X), then the M-th RS resource in the first RS resource set corresponds to the (M−1)K+1 to N-th RS resources.

Optionally, the order in which {C₁, . . . , C_(M)} and {I₁, . . . , I_(N)} are arranged may be an order arranged in the corresponding RS set, or an order arranged according to the corresponding resource ID size.

In the third type mode: the first RS resource set includes M RS resources {C₁, . . . , C_(M)}, and the second RS resource set includes N RS resources {I₁, . . . , I_(N)}.When configuring the first and/or second RS resource set, the base station configures the resources included in the first and/or second RS resource set in a grouping manner.

For example, the first RS resource set is divided into A groups, and the second RS resource set is divided into B groups, where 1≤A≤M and 1≤B≤N. The base station separately configures first RS resources included in each group of the A groups of the first RS resources, and/or the second RS resource included in each group of the B groups of the second RS resources. The first RS resource in an a-th group corresponds to the second RS resource in a b-th group, and a correspondence between such groups is configured by the base station or predefined. If A=B is pre-defined, the a-th group corresponds to the second RS resource in the b-th group; or if A=B=M is pre-defined, an m-th first RS resource corresponds to the second RS resource in an m-th group; or if A=B=N, an n-th second RS resource corresponds to the first RS resource in an n-th group.

Exemplary Embodiment Four

This exemplary embodiment gives an implementation of CSI feedback. When a CSI feedback includes a CRI and/or a L1-RSRP, a terminal may measure and report the CRI and/or the L1-RSRP based on a triggered aperiodic reference signal. A base station triggers one or more reference signal resource sets through higher layer or physical layer signaling, and selects to report the CRI and/or the L1-RSRP based on the measurement on these reference signal resource sets. The base station triggers M reference signal resource sets, and an m-th reference signal resource set includes Km reference signal resources. There are Σ_(m=1) ^(M)K_(m)=K reference signal resources, modes of the base station feeding back the CRI include at least one of a mode 1, a mode 2 and a mode 3.

Mode one: encoding and reporting are performed according to an order of selected reference signal resources in K reference signal resources.

Optionally, the order may be an order of the reference signal resource set and a configuration of reference signal resources in each set, or an order of ID sizes of K reference signal resources.

Optionally, a feedback bit width of each CRI is [log₂(K)] bits.

Mode two: the reported CRI includes two parts, which are indication information of the reference signal resource set where the reference signal resource is located, for example, the indication information indicates that the reference signal resource set is information of an m-th set of all measured reference signal resource sets; and indication information that the reference signal resource is in a kth reference signal resource of the reference signal resource set in which the reference signal resource is located.

Optionally, the k-th reference signal resource and/or the m-th reference signal resource set are arranged in at least one of the following orders: an order configured according to the reference signal resource set, an order of the reference signal resource configured in the reference signal resource set, an order of the reference signal resource set ID size, and an order of the reference signal resource ID size in the reference signal resource set.

Optionally, the feedback bit width of each reference signal resource set indication information is [log₂(M)] bits, and the feedback bit width of each reference signal resource indication information corresponding to an m-th reference information resource set is [log₂(K_(m))]. Alternatively, the feedback bit width of each reference signal resource indication information in the m-th reference signal resource set is ([log₂(M)]+[log₂(K_(m))]) bits.

Mode three: the reported reference signal resource is the k-th reference signal resource in the m-th reference signal resource set, and the reported CRI is calculated according to the formula which is a function of k and m. For example, the reported CRI indicates information of a (Σ_(i=0) ^(m−1)K_(i)+k)-th resource among totally K resources, where m=1, . . . , M; k=1, . . . , K; and K₀=0.

In addition, when the CRI is x, the k-th reference signal resource in the m-th reference signal resource set is indicated, where m satisfies Σ_(i=0) ^(m−1)K_(i)<x+1, Σ_(i=0) ^(m)K_(i)≥x+1, k indicates x+1−Σ_(i=1) ^(m−1)K_(i), where m=1, . . . , M; k=1, . . . , K; K₀=0.

Optionally, the k-th reference signal resource and/or the m-th reference signal resource set are arranged in at least one of the following orders: an order configured according to the reference signal resource set, an order of the reference signal resource configured in the reference signal resource set, an order of the reference signal resource set ID size, and an order of the reference signal resource ID size in the reference signal resource set.

Optionally, a feedback bit width of each CRI is [log₂(Σ_(m=1) ^(M)K_(m))] bits.

In addition, the triggered M reference signal resource sets, each set includes information indicating a time difference between a time slot for transmitting the reference signal and a time slot for the triggering signaling. When the M reference signal resource sets are triggered, the time difference indicated by each reference signal set may be different. For example, the time difference indicated by the M sets is M consecutive integers. In this case, each reference signal set may be represented by ID information of a time slot, for example, a 1st, a 2nd, . . . , an M-th reference signal resource set corresponds to a respectively one of a s₁-th, a s₂-th, . . . , an s_(M)-th time slot after the triggering signaling. In the methods for feeding back the CRI, parameters 1, . . . , M, etc. representing the reference signal resource set ID may be replaced with parameters such as s₁, s₂, . . . , s_(M), etc.
